> If HostSelectionPolicy continuously returns the same host that is downed it will lead to an endless query execution. It happens [here|https://github.com/apache/cassandra-gocql-driver/blob/9d6c255a97b75842925e52921120918aeb3f646f/query_executor.go#L158] when `hostIter` returns host is downed or nil which causes skipping of loop iteration.
> Potentially it may cause a goroutine stuck even if the context provided to the query is canceled. 
> Raised [here|https://github.com/apache/cassandra-gocql-driver/pull/1793#discussion_r1935766004]
